Why isn’t this a popular thing?
Because despite all of our modern technology we are still very much bound to the cycle of night and day. Right now if someone says ‘Hey let’s meet online at noon’ you have to ask what time zone they’re in and do a little dead-simple math to figure out what time that is for you. Oh you’re EST and I’m MST, noon for them is 10am for you. Not particularly hard, but a little irritating. On a system like you suggest you wouldn’t have to do a little addition/subtraction to figure out what time it would be for you, you instead have to do some more complex math based on when the sun comes up for you and figure out if you’ll even be awake at that time. You’re hosting a meeting on west-coast US time and one of the people in that meeting and they’re on the east coast of Australia. Noon your time and noon their time is the same, but for them noon happens at what might otherwise be in the middle of the night, so they’ll definitely be asleep.
Really this is the simplest version because we all still mostly wake and sleep with the sun.
Why calculate?
While 1200 might be noon for one, another might just get used to 0800 to be noon. Who says 0000 must be midnight and 1200 noon?
While 1200 might be noon for one, another might just get used to 0800 to be noon.
Aside from the fact that that’s just timezones with extra steps?
Who says 0000 must be midnight and 1200 noon?
Thousands of generations of human history/prehistory? We are used to being awake during the day because we use vision so much for everything we do, so we sleep when it’s dark.
You just recreated time zones
If I am set to arrive in Bejing at 18:00 UTC that gives me 0 useful information without calculation.
Knowing that I will arrive at 2am local time is much more useful, it tells me it’ll be dark and most shops won’t be open.
No idea, I’ve been using UTC both while travelling and at home (which is not located in the UTC time zone) and it is not significantly more difficult than using 24-hour time in a customarily 12-hour country.
Good luck teaching kids how to tell time then.
Like, the loose but accepted general concept of time as we tend to comprehend it best is when it’s noon, the sun is around its peak.
Using one single time worldwide would totally break that concept and make things very confusing.
Idk if it would. As a pilot, Zulu time (gmt 00:00) is used across the board.
The person was rather talking about locally significant understanding of time like “I have to wake up at 4AM for fucks sake.”, which has the same meaning anywhere at any time.
But if the same time as 4am now fell on 20:00 people locally would know its super early
Which would make moving or travelling between time zones confusing. Exactly the problem op wishes to solve. Have they considered when the day moves from Monday to Tuesday? Is that at midnight still?
20:00? That’s a reasonable time here. Businesses here are usually open from 23:00-10:00.
Thank goodness it’s Thursday, though, the weekend is about to start.
Last I checked, kids aren’t pilots. You’re speaking from a rather advanced concept of worldwide time.
How would you even teach a 5 year old how to tell basic time to begin with?
I imagine not too differently to the way you do now, except the numbers would be different. “Every day the Sun comes up at 4pm and sets 12 hours later. Other places it rises and sets at different times. i think the bigger issue for everyone would be 12am hitting during the day. You can’t just say you’re going to do something on a given Tuesday if every day switches over at 2pm or whatever. You’d probably need some kind of time zone either way to handle it.
Fun personal fact about me: I didn’t learn to tell time until I was 9 years old. I was effectively blind until I was 8 when I first got glasses, so I had never actually seen a clock before then.
Don’t get me wrong, I already had a concept of time, every time my parents or teachers would say the time numerically, but I simply never actually saw a clock in person until the year after I finally got glasses.
One day when I was 9, my parents left me home alone to briefly go to the local store. Still dumbfounded by my new glasses and how clearly I could see stuff, I started looking at stuff on the walls.
Then I saw the analog clock, just ticking away. I sat there for 5 minutes, just staring at it, counting every single tick of the second hand, and carefully paying attention to the slow movement of the minute hand.
Then I thought to myself ‘Well shit, now I get it!’
I more or less figured it out all on my own. But if it was somehow a confusing universal time as OP suggests/asks about, I wouldn’t have been able to figure it out on my own and would have still been really confused.
I mean there’d still be clocks and they’d still read the same way, there just wouldn’t be any difference between what they say in different parts of the world.
Zulu time is a pilot?
As a software engineer, I express all time in seconds (plus fractional units as necessary) since The Epoch, which happens to be in UTC, which you might know as “Zulu time.” But that’s in order to keep a worldwide network interoperable, same as you.
Probably the same reason everyone doesn’t just talk English.
But that’s a pretty different matter.
Basically, it’s like if most people who speak English agreed to only talk in British English.
Even that is a completely different thing.
Even then, everyine speaking english would make more sense than removing timezones
Angry Brutish Empire noises
Because it rather tells time… sun-wise, if that explanation makes sense. If you want something worldwide for some large event, you simply mention the timezone.
What we should eliminate is summer and winter time.
Time is confusing. We should all just use Unix Timestamp. Meet me at 1748918019!
That’s literally how computerized calendars work, so unironically this
Are we could use .beat time
I’m a fan of Swatch Internet Time myself!
Once upon a time, when airplanes where not a thing and real time communication implied a distance that you can scream to… When only snail mail or telegraph where available and people traveled by boat and train…
You would never experience jet lag nor have the problem of knowing if people far away was ssleeping or not.
In this scenario, when time was standardized and organized, it only made sense that everybody would wake up and go to bed at the same time no matter where their lived (more or less, of course ,you get the meaning). Thats when time zones where defined, so that people traveling by boat or train would keep waking up day after day at the same time of the day.
Without time zones, life would be quite difficult to organize and understand. Ask to the Chinese, that live in the Beijing timezone in a country spanning three time zones. They keep using mixed local and Beijing times… And catching trains and airplanes is a mess for this reason…
No, timezones are really needed. Not having them would be weird and messy.
I would venture to guess it had to do with noon. It would have always been easy to say sunrise, sunset or noon even before a clock or sundial were invented. Remember there were no aircraft flying through the timeshifts. The effects of time on long distance travel were negligable if noticeable at all. Communications also traveled slowly. Once technology introduced clocks, you could see how your noon no longer aligned with the sun a couple hundred miles east or west. Your clock would not match the place you are visiting as noon had hands both pointing straight up as where the sun would also be located at that time. Your question only becomes relevant when we get light speed communication like radio and telegraph.
“Good afternoon German friend how is the weather today?” “WHY ARE YOU RINGING ME IN THE MIDDLE OF THE NIGHT, AMERICAN FRIEND!?” Not a real conversation, but you can imagine.
The answer: people hate change.
After reading the lack of consensus in the comments, I’ll just be over here using decimal time, confusing everyone around me. ;)
They do on their servers. For human activities, having times relative to the diurnal cycle makes more sense than having to do the mental arithmetic.
Because my noon is the best noon, and your silly noon is unreasonable. It happens at 4am, you silly goose.
Why arent we using only X because Y is inefficient.
Fantastic article. Never seen it. Thanks for sharing!
-
Day/night cycle, the local time usually matches with the local day/night cycle which is far more relevant than international communication of time
-
Tradition, some countries have weird time zones, but it’s a lot of effort for little gain to change that
Even though there is a day night cycle, the time for sunrise varies by location anyways (and they also change during different time of the year)
We already arbitrarily decide a number to be “morning” anyways, what’s the harm in having each place have their own time range for “morning”?
It’s mostly with how society decides that the standard office hours is 9-5, if we are not restricted by such constraints, then it really matters less.
at some point we would have to shift the date and it’s much more convenient to do that at night
